Tire models such as Pacejka, Fiala etc are the basis for commercial tire codes bundled with Altair Simulation. Nearly all are empirically derived, which means that real tires are tested and the raw data is fitted to produce the co-efficients necessary to populate the tire model of choice. It may therefore become necessary…
The goal of this article is to show the process of taking road obstacle data given in excel for the left and right tires, then importing it into an nPost simulation. In addition, the process of scaling the events data based off of the speed, wheelbase and course length.
When creating force outputs on components like Bodies. There is an option to export the loads acting on the components at defined timesteps. This can be exported either as a readable text file or as a Nastran file for FEA analysis. This is the Load Export Tool found in the Flex Tools menu in MotionView. The attached video…
By default in MotionView, the vehicle's reference frame is consistent with the reference frame used by practically all vehicle manufacturers. This is known as SAE format. Where the positive Z axis direction is the vehicles up direction, the positive Y axis direction is the vehicle's right direction and the positive X axis…
The Goal of this article is to show how to properly export and import systems to other models. You would also use this workflow if you wanted to merge models together.
